Gauge pin M323.438 — 4.38 mm, ±0.001 mm, 50 mm length (Metav IndustryLine)

Gauge pin M323.438 for precise hole and fit checks in production and inspection settings, designed as a workshop‑grade single pin.

• Diameter 4.38 mm, tolerance ±0.001 mm
• 50 mm length for accessible probing
• Workshop execution for repeated use
• Supplied in a protective transport case

Precision that reduces measurement uncertainty

A compact checking pin with ±0.001 mm tolerance delivers the kind of repeatable dimensional reference that streamlines inspection. The small 4.38 mm diameter combined with the 50 mm length makes this pin ideal for verifying bore sizes, dowel fits and mating features where end‑size control is critical. The very fine tolerance reduces ambiguity in pass/fail assessments and supports traceable quality records in routine checks.

Robust design for workshop routines

Manufactured from special steel, the single‑piece construction is optimised for repeated insertion and withdrawal during batch inspection cycles. The workshop execution balances stiffness and handling convenience, while the low mass aids rapid positioning in small bores. Delivery in a transport case protects the gauge during storage and transport, ensuring the geometry remains stable between uses and reducing the need for premature replacements.

Practical integration into quality workflows

This gauge pin is suitable for handheld verification as well as use in fixtures and gauging nests where a precise, immovable reference is required. Marking and traceability via the SKU support inventory management and calibration scheduling. As a compact, single‑element checking tool, it complements broader metrology kits and can be paired with calibrated masters for routine verification of end dimensions.
